The resulting solution was stirred for 30 minutes. The reaction solution was added to ethyl ether, and the resulting precipitates were collected by filtration to give a yellow powder (1.1 g).

To this powder was added anisole (8 ml), and trifluoroacetic acid (9 ml) was added dropwise over 30 minutes with stirring and ice-cooling, followed by stirring for another hour and a half. Ethyl ether was added to the reaction solution, and the resulting precipitates were collected by filtration. The precipitates were suspended in water (10 ml). The pH of the suspension was adjusted to 7 with sodium acetate. Insolubles were removed by filtration, and the filtrate was purified by reverse phase silica gel column chromatography to give the title product (30 mg).

The compound prepared in Experiment 6 (500 mg) was dissolved in a mixture of ethyl acetate (10 ml) and ethyl ether (10 ml). Dimethylglycinamide (160 mg) was added to the solution, followed by stirring at room temperature for 30 minutes. Isopropyl ether was added to the reaction solution. The resulting precipitate was collected by filtration and dried to give a tan powder (400 mg).

This powder was stirred in a mixture of trifluoroacetic acid (5 ml) and anise (4.5 ml) for one hour under ice-cooling. Ethyl ether was added to the reaction solution, and the formed precipitate was collected by filtration, followed by washing with ethyl ether. this precipitate was suspended in water (5 ml), after which the pH of the suspension was adjusted to 5.5 to 6.5 with sodium acetate. Insoluble matters were removed by filtration, and the filtrate was purified by reverse phase silica gel chromatography to give the title product (55 mg). The compounds of the following Examples 115-117 were prepared as described in Example 114.

The compound obtained in Experiment 4 (1.0 g) was suspended in ethyl ether (100 ml), and 1,4-dimethylpiperazine (8189 μl) in ethyl acetate solution (40 ml) was added dropwise thereto. then the solution was stirred overnight. The resulting precipitate was collected by filtration and reprecipitated from -106-89-169 tetrahydrofuran / ethyl acetate and washed with ethyl acetate to give a yellow powder (492 mg). This powder was dissolved in dichloromethane (2 ml), and methyl iodide (4 ml) was added thereto under ice-cooling, followed by stirring the solution overnight at the same temperature. The reaction solution was poured into ethyl acetate, and the formed precipitate was collected by refluxing to give a yellowish-brown powder (190 mg).

This compound was added to a mixture of trifluoroacetic acid (1.35 ml) and anisole (1.16 ml), and the solution was stirred for 2 hours under ice-cooling. The reaction solution was added to a mixture of ethyl ether (25 ml) and isopropyl ether (25 ml), and the resulting precipitate was collected by filtration and washed with ethyl ether. The resulting precipitate was suspended in water (4.5 ml), and insolubles were removed by filtration. The filtrate was purified by reverse phase silica gel column chromatography to give the title product (23 mg).

The compound obtained in Experiment 7 (1.43 g) was dissolved in acetone (20 ml), and sodium iodide (0.927 g) was added thereto under ice-cooling, and the solution was stirred for 10 minutes at the same temperature and further for 1.5 hours at room temperature. The solvent was evaporated, after which ethyl acetate was added to the residue, which was washed with dilute sodium thiosulfate solution -107-89169 and saturated brine, and dried over sodium sulfate. The brine was evaporated and the residue was dissolved in ethyl acetate (40 ml). To the resulting solution was added dimethylglycinamide (8237 mg), and the solution was stirred for one hour at room temperature. To the resulting solution was added iso-propyl ether, and the resulting precipitate was collected by filtration to give a yellowish-brown powder (1.07 g).

This compound was added to a mixture of trifluoroacetic acid (8 ml) and anisole (6 ml), and the solution was stirred for one hour under ice-cooling. Ethyl ether was added to the reaction solution, and the formed precipitate was collected by filtration. The precipitate was suspended in water (10 ml), then the pH of the suspension was adjusted to 5.5-6.5 with sodium acetate, and insolubles were removed by filtration. The filtrate was purified by reverse phase silica gel column chromatography to give the title product (268 mg).

The compound obtained in Experiment 4 (400 mg) was dissolved in ethyl acetate (4 ml), and 96 mg of triethanolamine in 4 ml of ethyl acetate was added thereto. The solution was stirred for 6 hours at room temperature. To the resulting solution was added 24 ml of isopropyl ether, and the formed precipitate was collected by filtration. This precipitate was added to a mixture of trifluoroacetic acid and anisole (1: 1) under ice-cooling. To the reaction solution was added 16 ml of diisopropyl ether. The formed precipitate was collected by filtration and washed with diisopropyl ether. The precipitate was suspended in water (3 ml), after which the pH of the suspension was adjusted to 6.0 with sodium acetate. Insoluble matters were removed by filtration, and the filtrate was purified by silica gel silica gel chromatography to give the title product (17 mg).

8.00 g of N-cyanomethoxyphthalimide was suspended in 50 ml of ethanol, and 1.93 ml of hydrazine monohydride was added thereto at room temperature. The resulting solution was stirred for 1 hour and 45 minutes. Saturated brine and ethyl ether were then added. The mixture was basified with concentrated ammonia and extracted with ethyl ether. The ethyl ether layer was washed with saturated brine and dried over anhydrous sodium sulfate. Finally, the solvent was evaporated off. To the residue were added 350 ml of methanol and 650 g of 2- (5-tritylamino-1,2,4-thiadiazol-3-yl) glyoxylic acid, and the resulting solution was stirred at room temperature for one hour.
